APPLICATION OF IMPEDANCE TOMOGRAPHY IN MECHANOTRONIC SYSTEMS WITH ULTRASONIC CAVITATOR

Abstract. In article is offered the technique of an estimation of presence and development degree cavitations to a liquid in pipes methods of an impedance tomography. For technique realization are used methods of reconstruction of an image with use of a method of final elements and a method of "zones" of conductivity on electric model of the phantom (tomography slice) in the form of squares of resistance with two diagonals and the "zones" consisting of these squares. Presence of the integrated zones provides radical reduction of usages of systems in systems of the equations of iterative procedure of Newton-Rafsona (at number increase reconstruction phantoms). Resolution of a method of reconstruction remains same, as well as for classic a method of final elements.
The problem of conditionality of a matrix derivative of transfer resistance on surface conductivity of the phantom is thus eliminated. The choice of the form of "zones" of conductivity defines accuracy of reconstruction at a various arrangement of heterogeneity in the phantom.
Keywords: cavitations, impedance tomography, reconstruction of an image, phantom, method of Newton-Rafsona, method of "zones" of conductivity, Derivatives of transfer resistance, the inverse problem, a finite element, on surface conductivity.
